- Apr. 21: Improvements to glider syntheses mean that every 15-bit still life has a recipe with at most 13 gliders. The upper limit is currently 12 gliders for 14-bit still lifes, 10 gliders for 13 bits, 8 gliders for 12 bits, and 7 gliders for 11 bits.
- Apr. 17: Tanner Jacobi and Matthias Merzenich set several new bounding-box records with a new glider gun mechanism based on filtered MWSSes.
- Apr. 10: Jeremy Tan releases a new glider recipe database, Shinjuku, specifically for tracking lowest-cost syntheses.
- Apr. 6-7: LifeViewer standardizes support for triangular neighbourhoods starting with Build 320.
- Apr. 5: An exhaustive computer search run by Nathaniel Johnston reveals that there are 14,223,867,298 strict and 15,851,861,075 pseudo 33-bit still lifes, including eleven pseudo still lifes that can be partitioned into three stable pieces but not two, and none that can be partitioned into four stable pieces but not two or three.
